I need to do the step 2 and 3

Step-by-step explanation:

STEP-2

MEAN-

1 List data set from least to greatest

2 Next add up all the numbers

3 Then divide that number by the amount of numbers you have(EXAMPLE (12,3,6,5)) you have 4 numbers add them up and divide by 4

4 then Solve and get your Mean

MEDIAN-

1 List numbers least to greatest

2 then you need to find which number is in the middle (EXAMPLE 12,3,6,5)

least to greatest 3,5,6,12,15 the middle number is 6

TWO OR MORE MIDDLE NUMBER

If there are 2 middle numbers  find the mean of those two numbers

Then solve to get your answer

RANGE-

1 List the order of numbers from least to greatest

2 then your range would be the biggest number and smallest number for example 3,5,6,12,15 the range would be 3,15

3(-7h -4) + 4(h -6)

-21h -12 + 4h - 24

-21h +4h -12 -24

-17h - 36
